563. ORTHOTOMUS SAMARENSIS Steere.
YELLOW-BREASTED TAILORBIRD.
- Orthotomus samarensis Steere, List Birds & Mams. Steere Exped. (1890), 20; Grant, Ibis (1897), 228; Whitehead, Ibis (1899), 220 (habits); Sharpe, Hand-List (1903), 4, 192; McGregor and Worcester, Hand-List (1906), 88.
Bohol (McGregor); Leyte (Whitehead); Samar (Steere Exp., Bourns & Worcester, Whitehead).
Adult male.—Entire head, neck, chin, throat, and middle of fore breast black; back and rump dull olive-green brighter around the neck; rump and tail-coverts dull russet-brown; wing-feathers blackish, edged with olive-green, the bend of wing and tips of greater median coverts yellow; rectrices brown, edged with russet; breast, sides of breast, and of neck, and abdomen lemon-yellow becoming olivaceous on sides, flanks, and crissum; thighs dull chestnut. The black of fore breast is sharply defined against the yellow, and does not extend over the sides of the chest as it does in O. nigriceps, but is confined to the central parts of the chest, its posterior outline being rounded. All the specimens known have more or less white on the chin and malar region, but this is variable in extent and is probably a sign of immaturity as it is in O. nigriceps. A male from Bohol measures: Length, 127; wing, 44; tail, 39; culmen from base, 15; bill from nostril, 11; tarsus, 21.
